16 E285 INSTALLATION GUIDE
The battery has a safety circuit to protect the Li-ion cells from overcharging and
over-discharging. If the battery is over-discharged, the safety circuit shuts down
the battery. The battery must then be recharged to restore operation.
The following table shows the behavior of the LEDs during various system power
states.
Battery Life
Charging and discharging the e285 battery hundreds of times will wear out the
battery. Significantly reduced operating times indicate the need for battery
replacement (see Accessories and Documentation for ordering information).
Connecting to a
Computer
Connect the e285 device to a PC or laptop to download applications.
To Connect to a
Computer
1 Insert the USB-C plug into the USB-C port of the e285, as shown in the figure
below.
2 Connect the other end of the USB-C plug into the host computer’s USB port.

NOTE
The e285 device automatically shuts off when the battery reaches the critically
low charge state. If this occurs, the battery must be recharged for a minimum of
1/2 hour before it can power the device. It may take several recharge attempts to
reset the safety circuit when charging a battery that has been discharged below
this critical state.
